Answer:
W = -262 J.
Explanation:
Hello there!
In this case, according to the given information, we can recall the definition of work in terms of constant pressure and variable volume as follows:

So we plug in the given pressure and volumes to obtain:

Now, we convert this number to J (Pa*m³) by using the shown below conversion factor:

Answer:
0.054 M
Explanation:
1 mol NaHSO4 -> 120 g
x ->13 g
x= 0.108 mol NaHSO4
M= mol solute/ L solution
M= 0.108 mol NaHSO4/ 2.00L
M= 0.054 M
