Answer:
3.01 x 10²¹
Explanation:
Molar mass of h₂o =18.01528 g/mol.
it means 1 mole h₂o=18.01528 g .....(1)
1 mole = 6.022 × 10^23 molecules
so,
1 mole h₂o =6.022 × 10^23 molecules=18.01528 g [from 01]
now,
18.01528 g h₂o has= 6.022 × 10^23 molecules
9.00x10⁻² g h₂o has= ( 6.022 × 10^23 x 9.00x10⁻² ) /18.01528 molecules
=3.008 x 10²¹ molecules
≈ 3.01 x 10²¹ molecules
Answer:
1370 °C
Explanation:
We can use the Ideal Gas Law and solve for T.
pV = nRT
Data:
p = 8.12 atm
V = 36.41 L
n = 2.19
R = 0.082 06 L·atm·K⁻¹mol⁻¹
Calculations

T = (1645 - 273.15) °C = 1370 °C
The temperature of the sample is 1370 °C.
