How many milliliters of sodium metal, with a density of 0.97 g/ml, would be needed to produce 53.2 grams of hydrogen gas in the single-replacement reaction below? show all steps of your calculation as well as the final answer.

na + h2o → naoh + h2

my
1. balance the equation: 2na + 2h2o --> 2naoh + h2
2. take the known amount of 54.2 g h2 and convert it into moles, multiply by the mole ratio (number of moles from the balanced equation, unknown substance over the given substance) and convert it back into grams:
53.2 g h2 x 1 mol h2/ 2 g h2 x 2 moles na/ 1 mol h2 x 22.98 g/ 1 mol na = 1222 g na
1 gram = 1 ml,
so 1222 ml of na

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.
