How many representatives particles are there in 1.45 grams of a molecular compound with a gram molecular mass of 237 grams?
To determine the number of representative particles in a sample of a molecular compound, you need to divide the given mass by its gram molecular mass, and then multiply by Avogadro's number (6.022 x 10^23 particles per mole). In this case, for 1.45 grams of a compound with a gram molecular mass of 237 grams, you would calculate (1.45 g / 237 g/mol) * 6.022 x 10^23 particles/mol to find the number of representative particles.
What Used to find the number of neutrons?
To find the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass number. Neutrons are uncharged particles found in the nucleus of an atom and their number can vary for a given element based on isotopes.
How do you find the number of neutrons when given a mass number?
Number of neutrons = Mass number - Number of protons
What is the element with104 neutrons?
Lutetium (Lu) has 104 neutrons To find this number for any element, take the atomic number (lutetium is 71 on the periodic table) and the mass number of the element and subtract to find neutrons. The atomic number represents the number of Protons and electrons in an atom, the mass number can be found by rounding the atomic mass. If you subtract the # of protons from the total it will tell you how many particles , or neutrons, are left in the nucleus of the atom.. The atomic mass of Lu is 174.967 amu Therefore 175 (total particles) -71 (proton particles)= 104 Neutron particles.
How many moles of Na SO4 are in 25.0 of this compound?
To find the number of moles of Na2SO4 in 25.0 g of the compound, you need to convert the mass to moles. First, determine the molar mass of Na2SO4, then divide the given mass by the molar mass to obtain the number of moles.
How many representatives particles are there in 1.45 grams of a molecular compound with a gram molecular mass of 237 grams?
To determine the number of representative particles in a sample of a molecular compound, you need to divide the given mass by its gram molecular mass, and then multiply by Avogadro's number (6.022 x 10^23 particles per mole). In this case, for 1.45 grams of a compound with a gram molecular mass of 237 grams, you would calculate (1.45 g / 237 g/mol) * 6.022 x 10^23 particles/mol to find the number of representative particles.
How many representative particles are in 1.45 g of a molecular compound with a molar mass of 237 g?
There are 6.02 x 10^23 representative particles (molecules) in 1 mole of a substance. To find the number of representative particles in 1.45 g of a compound with a molar mass of 237 g, you first need to determine the number of moles in 1.45 g of the compound using the formula: moles = mass / molar mass. Then, multiply the number of moles by Avogadro's number to find the number of representative particles.
How do you know when to solve for a empirical formula?
You should solve for an empirical formula when you are given the percent composition of elements in a compound or when you have the molar mass of the compound but not the molecular formula. The empirical formula provides the simplest whole-number ratio of atoms in a compound.
What Used to find the number of neutrons?
To find the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass number. Neutrons are uncharged particles found in the nucleus of an atom and their number can vary for a given element based on isotopes.
What is the rule you can use to find the number of quarts in a given number of pints?
1 quart = 2 pints To find the number of quarts in a given number of pints, divide the given number of pints by 2 .
How many moles of sodium sulfate are in 0.1000g of the compound?
To find the number of moles of sodium sulfate in 0.1000g of the compound, you first need to determine the molar mass of Na2SO4. Then, divide the given mass by the molar mass to get the moles.
What is a perfect squre number?
Given a number, if you can find another number (usually smaller than the given number) when multiplied by itself yields the original given number then the original given number is a perfect square number
How do you find a perimeter of a rectangle with one number given?
If you are given the area you will have to think what do you times with the number you have to get it.
How do you work out the number of moles of unknown compound if you are only given the molar mass?
To find the number of moles from molar mass, divide the mass of the compound by its molar mass. The formula is: Moles = Mass (g) / Molar Mass (g/mol). This will give you the number of moles of the unknown compound.
What is the molar mass of a compound if 25.0 g of the compound dissolved in 750 mL gives a molarity of 0.290 M?
First, calculate the number of moles of the compound using the given molarity (0.290 M) and volume (750 mL). Then, use the number of moles and the given mass (25.0 g) to find the molar mass of the compound using the formula: Molar mass = Mass / Moles.
How you find the oxidation number?
For a neutral atom or compound, the oxidation number is always 0. For an ion, the overall oxidation number is its charge. If you need to find an oxidation number to a particular atom of a compound, there are two ways: working out the Lewis structures or balancing the charges.
How many moles of MgCl2 are there in 317 g of the compound?
To find the number of moles of MgCl2 in 317 g of the compound, first calculate the molar mass of MgCl2 (95.21 g/mol). Then, divide the given mass by the molar mass to get the number of moles: 317 g / 95.21 g/mol = 3.33 moles of MgCl2.
