746mmhg, 115m^3, 21*c number of moles?

n = 4678.13 mol

Explanation:

Given data:

Temperature = 21°C

Pressure = 746 mmHg

Volume = 115 m³

Number of moles = ?

Solution:

21+273 = 294 k

746 /760 = 0.982 atm

115×1000 = 115000 L

PV = nRT

n = PV/RT

n =   0.982 atm × 115000 L /0.0821 atm. L. K⁻¹. mol ⁻¹× 294 k

n = 112930 atm. L/24.14 atm. L. mol ⁻¹

n = 4678.13 mol

explanation:

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
