Convert 277.3 mL at 50 mmHg to its new volume at 152 mmHg. A. 52.67 mL
B. 356.98 mL
C. 399.17 mL
D. 91.22 mL

D. 91.22 mL

Explanation:

Boyle's Law P₁V₁ = P₂V₂

                  (50mmHg)(277.3mL) = (152mmHg)(V₂)

                  V₂ = 13865/152mmHg

                  V₂ = 91.2170526 mL = 91.22 mL

that's what i got you can count the number of atoms

elements make up everything, and they combine to make compounds.

the answer is c
