23.0 + 60.0 = 83.0° C heat energy is required to raise
Answer : The mass of solute in solution is
.
Solution : Given,
Molarity = 0.730 M
Volume of solution = 1.421 L
Molar mass of sodium carbonate = 105.98 g/mole
Formula used for Molarity :

where,
w = mass of solute
M = Molar mass of solute
V = volume of solution in liter
Sodium carbonate is solute and water is solvent.
Now put the given values in above formula, we get the mass of solute in solution.

By rearranging the terms, we get

Therefore, the mass of solute in solution is
.
Answer:
the name for NO is nitrogen monoxide
Answer:
9g/cm^3 is the density
Explanation:
P = m/V
P = 18/2 = 9g/cm^3
(This is more of a physics question than chem btw)
Option c
water is non polar and can dissolve non polar compounds such as oil
water is unable to dissolve or mix with substances like oil therefore making the statement false
