Answer:
3.75 g.
Explanation:
<em>mass percent is the ratio of the mass of the solute to the mass of the solution multiplied by 100.</em>
<em />
<em>mass % = (mass of solute/mass of solution) x 100.</em>
<em></em>
mass of calcium nitrite = ??? g,
mass of the solution = 25.0 g.
∴ mass % = (mass of solute/mass of solution) x 100
<em></em>
<em>∴ mass of solute (calcium nitrite) = (mass %)(mass of solution)/100</em> = (15.0 %)(25.0 g)/100 = <em>3.75 g.</em>
Answer:
Periodic but not oscillatory
Explanation:
The Orbital motion of the earth around the sun is not an oscillatory motion as it is not a two and Fro motion about a mean position. But it is a periodic motion.
To determine the amplitude of a transverse wave, measure the highest amount of disturbance from the equilibrium that the wave experiences.
Answer: .150 moles of Ana
Explanation:
You just multiply 3.45 g of Na times the number of mole so in this case 1 mole divided by the grams it takes to make that mole. Which can be found on your periodic table it is the number right under the symbol of the element.
