Answer:

162.2 g/mol

Explanation:

Molar mass is defined as the mass in 1 mole of the substance. It is calculated by adding the molar mass of the substituents each multiplied by the subscript they have in the formula.

Thus, To calculate molar mass of nicotine having formula, $C_{10}H_{14}N_2$

Molar mass of C = 12.0107 g/mol

Molar mass of H = 1.00784 g/mol

Molar mass of N = 14.0067 g/mol

Thus, molar mass of nicotine = $12.0107\times 10+1.00784\times 14+14.0067\times 2$ = 162.2 g/mol

Answer:

0.228 L is the volume that the gas occupies after it is driedand stored at STP.

Explanation:

Pressure of the wet gas = $P=695 Torr=\frac{695}{760}atm=0.914 atm$

1 atm = 760 Torr

Pressure of water vapor = p = 0.0372 atm

Pressure of gas = $P_1=P-p=0.914 atm-0.0372 atm = 0.8768 atm$

Volume of wet gas = $V_1=287 mL=0.287 L$

1 mL = 0.001 L

Temperature of the wet gas = $T_1=28.0^oC=28.0+273 K=301 K$

Pressure of dry gas at STP = $P_2=1 atm$

Temperature of the dry gas at STP , $T_2= 273 K$

Volume of dry gas at STP = $V_2$

Using combined gas law:

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

$\frac{0.8768 atm\times 0.287 L}{301 K}=\frac{1 atm\times V_2}{273 K}$

$V_2=0.228 L =228 mL$

0.228 L is the volume that the gas occupies after it is driedand stored at STP.

In chemistry, attention is the abundance of a constituent divided by way of the total quantity of an aggregate. several types of mathematical descriptions may be prominent: mass concentration, molar concentration, range concentration, and quantity concentration.

it's miles the amount of solute dissolves in one hundred g solvent. If the attention of the answer is 20 %, we understand that there are 20 g solutes in one hundred g solution. instance: 10 g salt and 70 g water are mixed and the solution is ready. find awareness of the answer by means of percentage mass.
