Na has an atomic mass of 23.0g and O has an atomic mass of 16.0g. How many grams of Na are needed to completely react with 40.0g
dimulka [17.4K]
The grams of Na that are needed to complete  to react with 40..0 g of O2 is calculated as  below

find the moles of O2 used = mass/molar mass

= 40 g/32g/mol = 1.25  moles

write the reacting equation
4Na+ O2 = 2Na2O

by use of mole ratio between Na to O2 which is 4 :1

the moles of Na = 1.25 x 4 = 5 moles

mass of Na = mass x molar mass

=  5 moles x 23 g /mol= 115  moles

When dinitrogen pentaoxide, a white solid, is heated, it decomposes to produce nitrogen dioxide gas and
AysviL [449]

9.5314 L is the volume of nitrogen dioxide formed at 103.25 kPa and 22.75 °C.

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

Given data:

Oxygen produced - 1.618 gram

Decomposition of N_2O_5 takes place.

Find - Amount of NO_2 produced.

The decomposition reaction is as follows -

2N_2O_5--> 4NO_2 + O_2

Moles of O_2 gas =\frac{1.6}{16}  =0.1 moles.

1 mole of O_2 is produced from 2 moles of dinitrogen pentoxide

0.1 mole of O_2  will be produced from = 0.2 moles.

Now, 2 moles of dinitrogen pentoxide produce 4 moles of NO_2

NO_2 produced will be - 0.4 moles.

Weight of NO_2 produced - 0.4 X 46

Weight of NO_2  produced - 18.4 gram

Thus, grams of NO_2 produced are 18.4

Now calculate the volume of NO_2

Given data are:

P=103.25 kPa =1.01899827 atm

T= 22.75 °C +273 = 295.75 K

n=0.4 moles

V=?

R= 0.0821 liter·atm/mol·K

Putting the value in PV=nRT

V =  \frac{nRT}{P}

V =  \frac{0.4 \;moles \;X \;0.0821\; liter\;atm/\;mol \;K X \;295.75 \;K}{1.01899827 atm}

V= 9.5314 L

Hence, 9.5314 L is the volume of nitrogen dioxide formed at 103.25 kPa and 22.75 °C.
