How many liters of hydrogen gas are formed from the complete reaction of 1.04 mol of C? Assume that the hydrogen gas is collecte

Alisiya [41]

The volume is 2.23 liters of hydrogen gas.

<u>Explanation</u>:

moles of C = grams / molecular mass of C

= 1.04 g / 12.011 g/mol.

= 0.086

The ratio between C and H2 is 1 : 1

moles H2 = 0.086

V = nRT / p

= 0.086 x 0.08206 x 316 K / 1.0 atm

V = 2.23 L.

A sample of a substance has a mass of 27.3 grams and a volume of 7.0 centimeters3. The density of this substance is

lora16 [44]

Answer:

The density of the substance is 3.9 grams per cubic centimeter.

Explanation:

Given mass=27.3 grams

volume=7 cubic centimeter

We need to find the density.

Density of a substance can be calculated by dividing mass of substance by volume of a substance

$Density\ =\ \frac{mass}{volume}$

$\\Therefore\ density\ =\ \frac{27.3}{7} \ =\ 3.9\ \frac{gm}{cm^3}$

Hence Density of the substance is $3.9gm/cm^3$ .
