Well, one mole would be considered as 6.02 x 1023 (atoms). Which in the copper form, this would be considered to be as 63.66 grams of copper. Know, by knowing this information, we're now able to figured out the question.
53.3 ÷ (atoms) 6.02 x 1023 ...
Which as a result, we then have 2665 over.
Answer:
B
Explanation:
When it freezes, it will be a solid. The molecules will barely move, not as much as in the other answer choices.
Answer:
0.12M
Explanation:
A balanced equation for the reaction will go a great deal in obtaining our desired result. So, let us write a balanced equation for the reaction
HCl + NaOH —> NaCl + H2O
From the above equation,
nA (mole of the acid) = 1
nB (mole of the base) = 1
Data obtained from the question include:
Vb (volume of the base) = 30mL
Mb (Molarity of the base) = 0.1M
Va (volume of the acid) = 25mL
Ma (Molarity of the acid) =?
The molarity of the acid can be obtained as follow:
MaVa/MbVb = nA/nB
Ma x 25/ 0.1 x 30 = 1
Cross multiply to express in linear form
Ma x 25 = 0.1 x 30
Divide both side by 25
Ma = (0.1 x 30) / 25
Ma = 0.12M
The molarity of the acid is 0.12M
