Answer:

0.905 atm = 688 mmHg

Explanation:

Use dimensional analysis.

First determine the relationship between atmospheres and mmHg.

#"1 atm = 760 mmHg"#

There are two conversation factors:

#(1"atm")/(760"mmHg")# and #(760"mmHg")/(1"atm")#

Multiply the given atm in your question by the conversion factor with 760 mmHg in the numerator.

#0.905cancel"atm"xx(760"mmHg")/(1cancel"atm")="688 mmHg"#
