Calculate to three significant digits the density of boron trifluoride gas at exactly and exactly . You can assume boron trifluoride gas behaves as an ideal gas under these conditions.

The given question is incomplete. The complete question is :

Calculate to three significant digits the density of boron trifluoride gas at exactly −5°C and exactly 1 atm . You can assume boron trifluoride gas behaves as an ideal gas under these conditions.

The density of boron trifluoride gas is 3.08 g/L

Explanation:

To calculate the relation of density and molar mass of a compound, we use the ideal gas equation:

PV=nRT

P = pressure = 1 atm

V = Volume

n = number of moles

R = gas constant =0.0821 Latm/Kmol

T = temperature =

Number of moles (n) can be written as:

where, m = given mass

M = molar mass

where,

where d = density

The relation becomes:

PM=dRT  

Thus the density of boron trifluoride gas is 3.08 g/L

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
