What is the density of ammonia (NH3) at 273 K and 1.00 atm? 0.7601 g/L 0.982 g/L 1.23 g/L 2.43 g/L

lisov135 [29]

Answer:The density of ammonia ( $NH_3$ ) at 273 K and 1.00 atm is 0.75 g/L.

Explanation:

Temperature of the gas = T = 273 k

Pressure exerted by the gas,P = 1.00 atm

Volume occupied by the gas = V

Number of moles of gas = n

PV=nRT (Ideal gas equation)

$PV=\frac{\text{Mass of ammonia gas}}{\text{Molar mass of the ammonia}}$

$\frac{P\times \text{Molar mass of ammonia}}{RT}=\frac{\text{Mass of ammonia gas}}{V}=\text{Density of the gas}$

Density of the gas:

$\frac{1 atm\times 17 g/mol}{0.0820 L atm\mol K\times 273 K}=0.75 g/L$

The density of ammonia ( $NH_3$ ) at 273 K and 1.00 atm is 0.75 g/L.

Raquel has collected $3. 80 in nickels and dimes. She has exactly 48 nickels. How many dimes does she have?.

n200080 [17]

Answer:

14 dimes

Explanation:

48 nickels = 48 x .05 = $2.40

$3.80 - $2.40 = $ 1.40

$1.40 / .10 = 14 dimes
