Atomic Mass of Na is 23.0. This means that the mass of 1 mole of sodium is 23.0g.
Mass of 4.5mol of Na = 4.5 x 23.0 = 103.5g
45 grams, since the atomic mass of water is 18g.18 * 2.5 = 45
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 ==========================
96,27 g of sand contain 45 g of silicon (if the sand is pure silicon dioxide).

45/94.2 is 0.4777 moles
45 grams, since the atomic mass of water is 18g.18 * 2.5 = 45
45 mg contains approximately 1.956 moles of atomic sodium.
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 ==========================
There's a thousand grams in a kilogram, 45 grams is 0.045 kilograms.
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
450 grams
1kg = 1000g. Therefore, 45 x 1000 = 45000 grams.
6.25 kg/45 litres = 6250 grams/45 litres = 6250/45 grams per litre =138.88... gpl

That is 45 teaspoons.
There are 1000 milligrams in grams. Therefore, 45 grams is equal to 45 x 1000 = 45000 milligrams.
