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
Based on the information the ratio between the deficit and gdp as a percentage is 2.41%.
<h3>Ratio between the deficit and gdp:</h3>
Using this formula
Ratio between the deficit and gdp=Annual federal deficit/Gross domestic product×100
Where:
Annual federal deficit=$350 billion
Gross domestic product=$14,500 billion
Let plug in the formula
Ratio between the deficit and gdp=$350 billion/$14,500 billion×100
Ratio between the deficit and gdp=2.41%
Inconclusion the ratio between the deficit and gdp as a percentage is 2.41%.

Pythagorean theorem should be used to determine the length of any of the three sides of a right-angled triangle.
<h3>What is Pythagorean Theorem?</h3>
Pythagorean theorem can be defined as a fundamental mathematical equation in Euclidean geometry and it can be used to determine the length of any of the three (3) sides of a right-angled triangle.
Mathematically, Pythagorean's Theorem is given by this formula:
c² = a² + b²
<u>Where:</u>
<u>For example:</u>
c² = 3² + 4²
c² = 9 + 16
c² = 25
c = √25
c = 5 units.
