To convert the given number of moles of aluminum to grams, we need to use the molar mass of the element as the conversion factor. Aluminum has a molar mass of 26.981 g/ mol. The answer to this problem is b. <span>fraction: 26.981 g Al over one mol Al. </span>
Water because it's a polar and hexane which is a nonpolar solvent
Answer:
The answer to your question is 71.22 g
Explanation:
Data
Density = 19.3 g/cm³
Volume = 0.00369
mass = ?
Formula
Density =
Solve for mass
mass = density x volume
Process
1.- Convert volume from liters to cubic centimeters
1 l ---------------- 1000 cm³
0.00369l --------- x
x = (0.00369 x 1000 ) / 1
x = 3.69 cm³
2.- Substitution
mass = 19.3 x 3.69
3.- Simplification and result
mass = 71.22 g
