Answer:

6.3231 × 10^21 molecules

Explanation:

If the unknown gas is ideal then,

P = 616 mm of Hg = 0.810526 atm

T = 29°C = 302 K

R = 0.0821 atm L / (mol K)

n = PV / (RT)

= (0.810526 atm × 322 × 10^-3 L) / (0.0821 atm L / (mol K) × 302)

= 10.5 × 10^-3 mol

Number of molecules present in given gas

= 10.5 × 10^-3 mol × 6.022 × 10^23 molecules/mol

= 6.3231 × 10^21 molecules
