Question

Calculate the mass in grams of 0.800 mole of H2CO3.

1)49.6
2)23
3)78

Answer 1

what's the mass of ONE mole of \(H_2CO_3\)?

Answer 2

i dont know i suck at chemistry.

Answer 3

add the molar masses of all the pieces. look them up on a periodic table

Answer 4

M = 2* 1,008 + 32.07 + 4 * 16 = ?
2 H S 4 O

Answer 5

The mass of One mole of H2CO3 = 62.024

Now this is where I get confused, you can times 0.800 mole by 62.024. ( = 49.6)
or you can divide the 0.800 by 62.024 (= 77.53 rounds to 78)

so you have a 50/50 shot at being right.

Answer 6

Correct answer: a) 49.6
