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
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 do you count the atoms in a compound?
You would look at the chemical formula. The subscripts tell you how many atoms of an element are in one molecule or formula unit. Examples: H2O has 2 atoms of hydrogen and 1 atom of oxygen. C6H12O6 has 6 atoms of carbon, 12atoms of hydrogen, and 6 atoms of oxygen.

How many representative particles are in 1.45 g of a molecular compound with a molar mass of 237 g?
1.45 g of a molecular compound with a molar mass of 237 represents 1.45/237 or 6.118 X 10-3 mole. Assuming that "representative particles" in the question means "molecules", this is (6.118 X 10-3){Avogadro's Number} or 3.68 X 1021 molecules.
How to find the percent by mass of a compound in a given sample?
To find the percent by mass of a compound in a given sample, you need to divide the mass of the compound by the total mass of the sample and then multiply by 100. This will give you the percentage of the compound in the sample.
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 can one determine the empirical formula from given percentages of elements in a compound?
To determine the empirical formula from given percentages of elements in a compound, you first need to convert the percentages to grams. Then, divide the grams of each element by its molar mass to find the moles of each element. Next, divide the moles of each element by the smallest number of moles to get the simplest whole number ratio. Finally, use these ratios to write the empirical formula of the compound.
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?
1st convert mL to L: 750mL x (1L/1000mL)= 0.75L 2nd find the number of moles: 0.75L x (0.290mol/ 1L)= 0.2175mol 3rd now find the MM(Molar Mass): 25g x (1g/ 0.2175 mol) = 114.9 g/mol or 115g
