Molarity is expressed as the number of moles of solute per volume of the solution. For example, we are given a solution of 2M NaOH this describes a solution that has 2 moles of NaOH per 1 L volume of the solution. To calculate the moles of NaCl in 1.0 M of solution, we simply multiply the volume given of the solution.
moles NaCl = 1.0 M (0.100 L ) = 0.10 mol NaCl --------> OPTION B

<span>As the Sun sets, the moon rises with the tide that faces the
Earth fully exposed to sunlight. The moon has phases because of its orbit to
Earth which causes the portion we see illuminated to change. The new moon
occurs when the moon is positioned
between the earth and the sun. at full moon and third quarter or called
as the half moon, it happens when the moon is at a 90 degree angle with respect
to the earth and the sun. crescent refers to the moon that is less than half
illuminated by the sun. gibbous refers to more than half illuminated by the
sun. waxing means growing or expanding in illumination and waning means
shrinking or decreasing in illumination.</span>
The amount of heat required to purify the Al is 25.94 * 10^3 J
<h3>What is heat capacity?</h3>
The term heat capacity refers to the amount of heat required to raise the temperature of a substance by 1K. The aluminum was heated from 298 K to 933 K then it melted.
The total heat required is;
H = ncdT + nL
H = (1 * 24 * (933 - 298)) + (1 * 10.7 * 10^3)
H = 15.24 * 10^3 J + 10.7 * 10^3 J
H = 25.94 * 10^3 J
