Answer:- 0.0634 M
Explanation:
molarity is defined as the number of moles of solute in 1 L of solution
molar mass of Ni(NO₃)₂ - 182.7 g/mol
number of moles of Ni(NO₃)₂ - 5.80 g/ 182.7 g/mol = 0.0317 mol
number of moles in 500 mL - 0.0317 mol
therefore number of moles in 1000 mL - 0.0317 mol / 500 mL x 1000 mL/L
molarity of the solution is - 0.0634 M

Answer:
answer is quantitative .
Explanation:
Quantitative observations are made with instruments such as rulers, balances, graduated cylinders, beakers, and thermometers. These results are measurable.
The total percentage of sales of the Model A is 47.37%.
Based on the fact that the selling price of model B is 60% more than the selling price of model A, the calculation below helps show how many percent of the total sales the model A represents.
<h3>Calculations and Parameters</h3>
Given:
Model A: 9,000
Model B: 10,000
Thus, the Total sales = model A + model B
= 9 + 10
= 19
Therefore, the total percentage of sales of the Model A = 9/19 × 100
= 0.473684210526315 × 100
= 47.367%
