Answer:
3
Explanation:
In scientific notation, the number of integers in the first part will always be the amount of significant figures.
For example,
1) 1.542505 x 10^17 =7 significant figures
1) 1.54 x 10^17 =3 significant figures
Answer: The molarity of the borax solution is 0.107 M
Explanation:
The neutralization reaction is:
According to neutralization law:
where,
= basicity of 
= 2
= acidity of borax = 2
= concentration of = 1.03 M
= concentration of borax =?
= volume of = 2.07ml
= volume of borax = 20.0 ml
Now put all the given values in the above law, we get the molarity of borax:
By solving the terms, we get :
Thus the molarity of the borax solution is 0.107 M
Answer:
Explanation:
Energy can come in many different forms such as mechanical energy, sound energy, electromagnetic energy, thermal energy, chemical energy, and nuclear energy.
15 Energy is measured in units called __________
.412 g Mn304/ 1mol * 1 mol Mn304/228.82(MM of Mn3O4 molecule)* 3 mol Mn/1 mol Mn3O4 = .00540 mol Mn *54.94 g/mol = .296 g Mn
I think the answer is A. The speeds of individual molecules varies.
