What does Q1 and Q3 mean in math?
maybe it is question 1 and question 2
What is Two times the sum of a number and three is five more than the number?
Let the number be x and if you mean 2x+3 = x+5 then the value of x is 2
What does the number 8563 mean?
Its mean the number 8563 !
What does a negative number in brackets mean?
It means that you treat it as a negetive number instead of as "minus one".For example:3-1=2But:3(-2)=-6.
What is the mean of 7 8 8 2 10 8 7?
Take the sum of the numbers divided by the number of numbers. Mean = (7+8+8+2+10+8+7)/7 = 7.14
How many chloride atoms are in MgCl2?
There are two chloride atoms in MgCl2, as indicated by the subscript "2" in the chemical formula.
What is the oxidation number of chlorine in MgCl2?
The oxidation number of chlorine in MgCl2 is -1. Magnesium is a group 2 element with an oxidation number of +2, and since the compound is neutral, the total oxidation number of the two chlorine atoms must equal -2, making the oxidation number of each chlorine atom -1.
How many atoms are n 4.0 moles of MgCl2?
In 4.0 moles of MgCl2, there are approximately 1.45 x 10^24 atoms. This can be calculated by multiplying Avogadro's number (6.022 x 10^23) by the number of moles (4.0) and then multiplying by the total number of atoms in one molecule of MgCl2 (3).
What is the net equation of Mgcl2 with NaOH?
The net equation for the reaction between MgCl2 and NaOH is: MgCl2 + 2NaOH -> Mg(OH)2 + 2NaCl
105 g of MgCl2 contains how much mol MgCl2?
First, we calculate the molar mass of MgCl2, which is 95.21 g/mol. Then, we divide the given mass by the molar mass to determine the number of moles of MgCl2. So, 105 g of MgCl2 contains approximately 1.10 moles of MgCl2.
How many formula units make up 11.6g of mgcl2?
To find the number of formula units of MgCl2 in 11.6g, first calculate the molar mass of MgCl2 (95.21 g/mol). Then, divide the given mass by the molar mass to find the number of moles (0.122 mol). Since 1 mol of MgCl2 contains 1 formula unit, the number of formula units in 11.6g of MgCl2 is also 0.122 mol.
124 g of MgCl2 contains __.mol MgCl2?
Mgcl2 contain molar mass=24.31+ 2(35.45)= 95.21 g/mol 124g of Mgcl2 contains moles= 95.21* 124=11806.04moles
What does MgCl2 mean in the periodic table?
Magnesium Chloride
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.
What is the formula of a compound formed when mg plus 2 and cl- react?
The compound formed when Mg^2+ and Cl^- ions react is magnesium chloride, which has the chemical formula MgCl2.
Does 1 mole of NaCl and 1 mole of MgCl2 have equal number of ions?
No, 1 mole of NaCl will produce 2 ions (1 Na+ and 1 Cl-) while 1 mole of MgCl2 will produce 3 ions (1 Mg2+ and 2 Cl-), so they do not have an equal number of ions.
How many atoms are on one mole of MgCI?
To determine the number of atoms in one mole of MgCl2 (magnesium chloride), you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms/molecules per mole. First, you need to calculate the molar mass of MgCl2. Magnesium (Mg) has an atomic mass of approximately 24.31 g/mol. Chlorine (Cl) has an atomic mass of approximately 35.45 g/mol (rounded to two decimal places). Now, add the atomic masses of one magnesium atom and two chlorine atoms to find the molar mass of MgCl2: MgCl2 molar mass = (1 x Mg atomic mass) + (2 x Cl atomic mass) MgCl2 molar mass = (1 x 24.31 g/mol) + (2 x 35.45 g/mol) MgCl2 molar mass = 24.31 g/mol + 70.90 g/mol MgCl2 molar mass = 95.21 g/mol So, the molar mass of MgCl2 is approximately 95.21 g/mol. Now, using Avogadro's number, you can calculate the number of atoms in one mole of MgCl2: Number of atoms in 1 mole of MgCl2 = 6.022 x 10^23 atoms/molecules per mole Now, divide this by the molar mass of MgCl2 (95.21 g/mol): Number of atoms in 1 mole of MgCl2 = (6.022 x 10^23 atoms/mol) / (95.21 g/mol) Number of atoms in 1 mole of MgCl2 ≈ 6.32 x 10^21 atoms So, there are approximately 6.32 x 10^21 atoms in one mole of MgCl2.
