Answer:
Step-by-step explanation:
The density formula is
Rearrange the formula for v. Multiply both sides of the formula by v, then divide both sides by d.
The volume can be found by dividing the mass by the density. The mass is 7525 grams and the density is 1.25 grams per milliliter.
Divide. Note that the grams, or "g" will cancel each other out.
The volume of the rock is 6,020 milliliters.
Answer:
B
Step-by-step explanation:
(-4-5)/(2-(-4))
= -9/6
= -3/2
hope this helped!
13. To find the angle of WZY you would have to grab the angle of a straight line (180) and subtract it from the already shown angle of 105. 180 - 105 = 75. 75 is the measure of WZY
14. WZ has a measure of 24 since the parallel side is also 24 (not too sure about this one)
15. XYZ Has the same angle as its corresponding angle of 105. The angle is also 105
The number of grams present in 0.54 moles of calcium is; 22 g
We are given;
Number of moles; n = 0.54 moles
Now, Molar mass of calcium is;
M = 40.1 g
Formula for number of moles is;
n = m/M
Where;
n is number of moles
m is mass in grams
M is molar mass
Thus;
0.54 = m/40.1
m = 40.1 × 0.54
m = 21.654 g
Approximately m = 22 g
