<u>Given:</u>
# Molecules of NaOH = 1.50 * 10²³
<u>To determine:</u>
The # moles of NaOH present in the given molecules
<u>Explanation:</u>
By definition:
1 mole of NaOH corresponds to Avogadro's number i.e. 6.023*10²³ molecules
Therefore the moles of NaOH corresponding to the given molecules would be = 1.50*10²³ molecules NaOH * 1 mole NaOH/6.023*10²³ molecules NaOH
= 0.249 moles
Ans: 0.249 moles of NaOH
Answer:
i really don¨ẗ know this one what grade are you in
Explanation:
Answer:
2°C.
Explanation:
Considering the thermometer used in this case, we can see that there are 5 lines counting from 0 to 10.
It therefore means that 1 line indicates 2°C.
With the above insight, the thermometer reads 2°C.
Therefore, the temperature of the water is 2°C.
The molar mass, in grams, of a mole for an element is equal to the atomic weight if the element.
