How many moles are in 45 grams of potassium oxide?
45/94.2 is 0.4777 moles
How many moles in 55g of lithium chloride?
AnswerTo find this answer, you need to know the molar mass of the compound. Find the weights of the elements involved, and add them up.Lithium chloride = LiClLithium = 6.94 gramsChlorine = 35.5 gramsLithium chloride = 42.2 gramsThen follow the conversion process:Grams ÷ Molar mass = Moles55.0 grams ÷ 42.4 grams = 1.30 moles LiCl See links below.

How many grams are in 2.50 moles of H2O?
45 grams, since the atomic mass of water is 18g.18 * 2.5 = 45
Which has the greatest number of atoms- 45 grams of Mg 45 grams of F 45 grams of P or 45 grams of Na?
In order to figure out how many atoms are in each sample, you would take 45, multiply it by 6.02 × 1023, and divided by the atomic mass. Since two of the numbers (45 and 6.02 × 1023) will be constants in all of the samples, the number of atoms will differ in each sample due to the atomic mass. 45 × (6.02 × 1023) / atomic mass in grams = number of atoms You could punch out all the numbers to see which sample has the greatest number of atoms, but it is easier to find the atomic mass for all of them and see which one is smaller. A larger atomic mass will mean the equation will be divided by a larger number, meaning the number of atoms will be smaller. So the smallest atomic mass would yield more atoms.Atomic masses:Mg- 24.3 grams***F- 38.0 gramsP- 31.0 gramsNa- 23.0 grams***Note that fluorine is a diatomic moleculeThe sample of 45 g of sodium (Na) would contain the greatest number of atoms
How many atoms in sugar?
45 atoms
How many grams of carbon dioxide would be produced if 45 g of C6H12O6 competely reacted with oxygen?
C6H12O6 + 6O2 --> 6CO2 + 6H2O 45 grams C6H12O6 (1 mole C6H12O6/180.156 grams)(6 moles CO2/1 mole C6H12O6)(44.01 grams/1 mole CO2) = 66 grams carbon dioxide produced ==========================
How many atoms does one molecule of table sugar have?
Table sugar has the chemical name and formula of sucrose (C12H22O11). For every one mole of sucrose, 12 moles of carbon are contained. In order to calculate moles you take 12 multiplied by Avogadro's number of 6.0221413 x 10^23. That would equal 7.2x10^24 atoms of carbon per molecule of sucrose.

How many molecules are in 4.21 grams of water?
45 grams H20 x (1 mole H20/18 grams H2O) x (6.02E23 molecules H20/1 mole H2O) the grams H2O and moles H2O cancel out. When you punch it into your calculator, the answer comes out to: =1.505E24 molecules H2O
How many grams are there in 45 percent of a kilogram?
450 grams
How many grams are there in 45 kg?
1kg = 1000g. Therefore, 45 x 1000 = 45000 grams.
