answer: 296 K

steps:

mass times temperature =mass times temperature

-51 * 300 = 29 * -290

300 * 51 = 15300

290 * 29 = 8410

-51x + 15300 = 29x - 8410

51 + 29 = 80

15300 + 8410 = 23710

23710 = 80x

80x = 23710

x = 296.375

kakasveta [241]

Answer:

The volume will be 89.6875 ml

Explanation:

So to count this we will use a single proportion.

0.0640 mol - 1000 ml

5.74×10−3 mol - x ml

x ml=5.74×10−3 mol*1000 ml/0.0640 mol=89.6875 ml

Explanation:

Applying PV= nRT

P= 1atm, V= 32.6L, R= 0.082, T = 273K

Substitute and simplify

1×32.6/(0.082×273)=n

n= 1.46moles
