Explanation:
Answer:The formula of magnesium chloride is MgCl2 . The molar mass of MgCl2 is (24.30 + 2 × 35.45) g/mol=95.20 g/mol .
Explanation:
The answer to this question would be: 11.5 grams
The molecular mass of hydrogen is 1, oxygen is 16 and carbon is 12. Then the molecular mass of CH4O would be: 12 + 4(1) + 16= 32.
To find the hydrogen mass, you just need to divide the hydrogen with total mass, resulting in the mass ratio of hydrogen to the compound. Then the amount of hydrogen inside 92 gram of CH4O are: 92grams * (4/32)= 11.5 grams
Answer:
What make Boron Boron is that it has 5 protons, and will therefor have 5 electrons in the unionized state. While I was looking this up I learned that there are two stable isotopes, Boron 10 with five neutrons, and boron 11 with six. The more common is boron 11, which is 80.1% of naturally occuring boron.
