1.35 moles

Explanation:

Assuming the gas is ideal, we can solve this problem by using the following equation:

PV = nRT

Where:

P = 812 torr ⇒ 812 / 760 = 1.08 atmV = 31 Ln = ?R = 0.082 atm·L·mol⁻¹·K⁻¹T = 30 °C ⇒ 30 + 273.16 = 303.16 K

We input the data:

1.08 atm * 31 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 303.16 K

And solve for n:

n = 1.35 mol

a - carbon is not toxic to living things

Explanation:

The reason carbon dating works is that the fresh carbon-14 gets mixed in with the rest of the carbon in the atmosphere and, since it's chemically identical to regular carbon, gets worked into whatever is presently absorbing atmospheric carbon
