Calculate the volume of 38.0 g of carbon dioxide at STP. Enter your answer in the box provided. L

Free_Kalibri [48]

Answer:

19.3 L

Explanation:

V= n × 22.4

where V is volume and n is moles

First, to find the moles of CO2, divide 38.0 by the molecular weight of CO2 which is 44.01

n= m/ MM

n= 38/ 44.01

n= 0.86344012724

V= 0.86344012724 × 22.4

V= 19.3410588502 L

V= 19.3 L

How many liters of 4M solution can be made using 100 grams of lithium bromide

uysha [10]

Molar mass of LiBr (mm )= 86.845 g/mol

Molarity ( M ) = 4 M

Mass of solute ( m ) = 100 g

Volume ( V ) = in liters ?

V = m / mm * M

V = 100 / 86.845 * 4

V = 100 / 347.38

V = 0.2875 L

hope this helps!.
