The number of n protons can be easily determined by its atomic number. With the atomic number and mass number (rounded If not already), then with basic subtraction we can calculate the number of neutrons...
Hope that helped!
Answer:
Zinc chloride is the name of chemical compounds with the formula ZnCl2 and its hydrates
Answer:
16.86%
Explanation:
Na3N is sodium nitride.
% of N = mass of N/ molar mass of Na3N *100
% of N = 14/83*100= 16.86%
35.453 (chlorine) + 10.811 (boron) = 46.264
<h2><u>Answer:</u></h2>
The correct answer is A) 1.04 mol Cu
{65.8 g / 63.55 g/mol}
= 1.04 mol Cu
Explanation:
In 63.55 g of copper metal there are 1 m
o
l of C
u atoms. By dividing the mass of Cu and molar mass, we can easily get the number of moles.
