Answer:
55.1 g Si.
Explanation:
Hello there!
In this case, for the given mole-mole relationship, it is possible to set up the following mole ratio as the moles of Si and P are the same:
1 mol Si = 1 mol P.
Next, since one mole of silicon has a mass of 28.09 g and one of phosphorous of 31.0 g, we can set up the following expression for the mass of silicon:
Therefore, the result is 55.1 grams of silicon.

Answer:
1.95 M
Explanation:
Molarity is a measure of the molar concentration of a substance (solution). In relation to the volume, it is calculated using the formula as follows;
C1V1 = C2V2
Where;
C1 = initial concentration (M)
C2 = final concentration (M)
V1 = initial volume (L)
V2 = final volume (L)
According to the provided information in this question;
C1 = 14.38 M
C2 = ?
V1 = 1.28 L
V2 = 9.45 L
Using C1V1 = C2V2
14.38 × 1.28 = C2 × 9.45
18.4064 = 9.45 C2
C2 = 18.4064 ÷ 9.45
C2= 1.95 M
