Question

What is the mass in gram of 1.0×10^23molecules of H2S

Answer 1

Answer:

Explanation:

mass of 1 H2S molecule is 2+32=34amu (2 hydrogen atoms and 1 sulfur atom)

so mass of 1 x 10²³molecules is 1 x 10²³ x34 amu

for converting amu into grams

1 amu = 1.66 x 10⁻²⁴

1 x 10²³ x 34 amu x 1.66 x 10⁻²⁴ =  5.64 grams

hope that it helps!!!
