Answer:
about 14.7 pounds per square inch
(atm) unit of measurement equal to air pressure at sea level, about 14.7 pounds per square inch. Also called standard atmospheric pressure.
The molar heat capacity is the heat capacity per unit amount (SI unit: mole) of a pure substance and the specific heat capacity, often called simply specific heat, is the heat capacity per unit mass of a material.
The accuracy of an indicator’s end point depends on the relative strength of the metal–indicator complex and the metal.<span>Unfortunately, because the indicator is a weak acid, the color of the uncomplexed indicator also changes with pH.</span>
Answer:
One billion
Explanation:
A nanometer is a BILLIONTH of a meter which means it takes one billion to equal a meter
Answer is: dissolve 74,9 grams CuSO₄·5H₂O in one liter volumetric flask.
V(CuSO₄·5H₂O) = 1 L.
c(CuSO₄·5H₂O) = 0,30 mol/L.
n(CuSO₄·5H₂O) = V(CuSO₄·5H₂O) · c(CuSO₄·5H₂O) .
n(CuSO₄·5H₂O) = 1 L · 0,3 mol/L.
n(CuSO₄·5H₂O) = 0,3 mol.
m(CuSO₄·5H₂O) = n(CuSO₄·5H₂O) · M(CuSO₄·5H₂O).
m(CuSO₄·5H₂O) = 0,3 mol · 249,7 g/mol.
m(CuSO₄·5H₂O) = 74,9 g.
