Answer:
The answer to your question is letter E. 288.4 g/mol
Explanation:
Data
Number of carbons = 19
mass percent of carbon = 79.12
molar mass = ?
Process
1.- Calculate the molar mass of 19 atoms of carbon
Atomic mass of carbon = 12 g
Atomic mass of 19 atoms of carbon = 228 g
2.- Use proportions to calculate the mass of testosterone
228 g --------------- 79.12 %
x -------------- 100 %
x = (228 x 100) / 79.12
Simplify
x = 22800 / 79.12
Molar mass of testosterone = 288.2 g
Answer:
Explanation:
Hello!
In this case, given the chemical reaction:
In such a way, given the volumes and molarities of each reactant, we can compute the moles of produced iron (III) hydroxide by each of them, via the 3:1 and 1:1 mole ratios:
It means that the sodium hydroxide is the limiting reactant and 0.00833 moles of iron (III) hydroxide are produced; thus, the required mass is:
Answer:
they both gain one electron
Explanation:
they are both halogens and they each have one unpaired electron so that unpaired electron join together to make them form a bond
Answer:
6
Explanation:
number of protons equal number of electrons for the atom to be stable
