What is the mass of 0.561 mol of the element potassium?
40*0.561=22.44g
What is the mass percentage of each element in the compound sodium hydroxide?
Molar mass Na: 23 g/mol O : 16 g/mol H : 1 g/mol Total NaOH: 40 g/mol Mass percentage %Na: 23/40 = 57.5% %O : 16/40 = 40% %H : 1 /40 = 2.5%

How many moles are there in 37 grams of calcium hydroxide?
Use the equationmol = mass / RFM (or RAM)mol = 37 / (40 + 16x2 + 1x2)mol = 37 / 74mol = 0.5
How many grams of sodium are in a 1 mole sample of sodium?
The molar mass of an element corresponds to the atomic mass of the element (found on the periodic table). The atomic mass of Sodium-Na is 22.990 g, which is also the molar mass of Na. So for 1 mole of Na, there are 22.990 grams of Na. If we had 3 moles of Na, then we would simply multiply the molar mass by 3.
How many grams of sodium hydroxide are there in 0.150 mol?
The molecular weight of sodium hydroxide is 40. Therefore 0.150 moles would be 40 x 0.15 = 6g.
How many grams of MgO are produced when 40 grams of 02 react with Mg?
:Mg: (2.43 g)/(24.3 g/mol) = .1 mol :MgO: (.1 mol)(24.3+16.0 g/mol) = 4.03 g
What is the mass percentage of each element in the compound sodium hydroxide?
Molar mass Na: 23 g/mol O : 16 g/mol H : 1 g/mol Total NaOH: 40 g/mol Mass percentage %Na: 23/40 = 57.5% %O : 16/40 = 40% %H : 1 /40 = 2.5%

What is the gram formula mass for Ca3PO42?
Ca = 40 x 3 = 120 grams P = 31 x 2 = 62 grams O = 16 x 8 = 128 grams Add them together and you have 310 grams. This is the mass in grams of your formula. It is expressed in grams/mole because 310 is the weight of one mole of Ca3(PO4)2.
How many oz are in 40 gram?
40 ounces = 1,133.98 grams.
