What volume of solution would be present if 40.0 g Caci, would be used to make a 0.600M

True [87]

Answer:

$\large \boxed{\text{601 mL}}$

Explanation:

1. Calculate the moles of CaCl₂.

$\text{Moles} = \text{40.0 g} \times \dfrac{\text{1 mol}}{\text{110.98 g}} = \text{0.3604 mol}$

Step 2. Calculate the volume of CaCl₂ solution

$\begin{array}{rcl} n &= &\dfrac{c}{V}\\\\\dfrac{\text{0.600 mol}}{\text{1 L}} &=& \dfrac{\text{0.3604 mol}}{V}\\\\ \dfrac{0.600V}{\text{1 L}} & = & 0.3604\\\\0.600V &= & \text{0.3604 L}\\V & = & \dfrac{\text{0.3604 L}}{\text{0.600 L}}\\\\ & = & \text{0.601 L}\\& = & \textbf{601 mL}\\\end{array}\\\text{The volume of the solution would be $\large \boxed{\textbf{601 mL}}$}$

Rebekah finds that a solution of sugar in water has a volume of 1. 32 fl. Oz. How should she report this amount using the metric

goldfiish [28.3K]

Rebekah reports the volume of sugar solution using metric system as 39.1 mL. Thus, option D is correct.

The metric system has been the measurement system introduced in 1790s. The system has mediated the units for the measurement of volume, mass, length.

The volume has been the space that has been occupied by matter. The volume can be denoted with SI unit L. However, the another accepted unit for volume has been mL.

Thus, the volume of sugar solution has been reported in mL.

The given sugar solution has volume of 1.32 fl. Oz

The volume in mL can be given as:

$\rm 1\;fl\;Oz=29.6\;mL\\1.32\;fl\;Oz=1.32\;\times\;29.6\;mL\\1.32\;fl\;Oz=39.1\;mL$

The volume of the sugar solution reported by Rebekah on the metric scale has been 39.1 mL. Thus, option D is correct.

A 0.941 gram piece of magnesium metal is heated and reacts with oxygen. the resulting oxide weighed 1.560 grams. determine the p

Whitepunk [10]

Given:

magnesium = 0.941 gram piece

Magnesium oxide= 1.560 grams

Formula:

(magnesium / magnesium oxide) x 100 = % Mg

100% - % Mg = percent composition of each element

Solution:

(0.941g Mg) / (1.560g MgO)

= 0.603

= 60.3% Mg

100% - 60.3%

= 39.7%

39.7% is the percentage composition of each element.
