number of moles = mass of the material/molar mass
1 mole is the molecular mass of a compound, element, ion in grams.
No. of moles = Mass (grams) x Mr
0.688 moles*6.02x1023=4.14x1023 Formula units
The answer is 5,978 moles.
If there is no number in front of the formula, the number of moles is understood to be one.
You use the formula concentration x volume to find out the number of moles
moles of acid = moles base = moles base/liter x liters of base used
0.688 moles*6.02x1023=4.14x1023 Formula units
The answer is 3,33 moles.
The answer is 5,978 moles.
The chemical formula of sodium chloride is NaCl; formula is not dependent from the number of moles. Because the molecular mass of NaCl is 57,958 622 382, the mass of 20 moles is 1159,172 447 64.
The formula is: number of moles = g Be/9,012.
If there is no number in front of the formula, the number of moles is understood to be one.
The result is 0,921.10e14 moles.
You use the formula concentration x volume to find out the number of moles
How many formula units of sodium acetate are in 0.87 moles of sodium acetat
C6H12O6 is the chemical formula of glucose (not sucrose !).The mass of 4.00 moles of glucose is 720,64 g.
The formula given shows that each formula unit or mole contains one calcium atom; therefore, 2.5 moles of calcium chloride contains 2.5 moles of calcium atoms.
moles of acid = moles base = moles base/liter x liters of base used
