Answer:

P=12.16 atm

Explanation:

Using the formula of ideal gas law:

PV = nRT

P= nRT/V

 n= number of moles

 R= Avogadro constant = 0.0821

 T= Temperature in K => ºC + 273.15 K

P= (1.50 moles)(0.0821)( 296.15 K)/ 3.00L

P= 12.15

tatyana61 [14]

Answer:

The molar mass of NaOH is 40.00 g/mol.

The number of moles of NaOH is equal to the ratio of its mass to molar mass.

The number of moles of NaOH =

40 g/mol

40 g

​

=1,000 mol

The molarity of NaOH solution is the ratio of number of moles of NaOH to total volume of solution in L.

M=

1 L

1 mol

​

=1 M
