Answer:
16.791 grams
Explanation:
The density formula is:
Rearrange the formula for m, the mass. Multiply both sides of the equation by v.
The mass of the gold nugget can be found by multiplying the density and volume. The density is 19.3 grams per cubic centimeter and the volume is 0.87 cubic centimeters.
Substitute the values into the formula.
Multiply. Note that the cubic centimeters, or cm³ will cancel each other out.
The mass of the gold nugget is 16.791 grams.
The answer would be
C) To reduce destruction by providing early warning of severe weather
This can help us because then we can plan our day-to-day activities better and can definitely help keep us out of danger.
well none its made from iron nut i would go with c. a solution sorry if im wrong tell me in comments
Answer:
0.978 M
Explanation:
Given data
- Mass of luminol (solute): 13.0 g
- Volume of the solution = volume of water: 75.0 mL = 0.0750 L
We can find the molarity of the stock solution of luminol using the following expression.
M = mass of solute / molar mass of solute × liters of solution
M = 13.0 g / 177.16 g/mol × 0.0750 L
M = 0.978 M
