A marble is L 1.32 W 1.32 H 1.32, what is the volume? Show your work
cupoosta [38]

The volume of the marble is 2.3 cube units.

From the question given above, the following data were obtained:

  • Length (L) = 1.32
  • Width (W) = 1.32
  • Height (H) = 1.32
  • Volume (V) =?

The volume of the marble can be obtained as follow:

V = L × W × H

V = 1.32 × 1.32 × 1.32

V = 2.3 cube units

Thus, the volume of the marble is 2.3 cube units.

1. How many mg of lithium phosphide are in 18.0 mL of a 1.25 M solution?
Temka [501]

Answer:

1160mg

Explanation:

Molarity = number of moles ÷ volume

According to the information in the question, molarity = 1.25 M, volume = 18.0 mL = 18/1000 = 0.018L

M = n/V

n = M × V

n = 1.25 × 0.018

n = 0.0225moles.

Using mole = mass/molar mass, to find the mass of lithium phosphide (Li3P)

Molar mass of Li3P = 6.9(3) + 31 = 51.7g/mol

mole = mass/molar mass

0.0225 = mass/51.7

mass = 1.16grams.

In milligrams (mg), mass of Li3P = 1.16 × 1000 = 1160mg
