Imagine we have <span>mass of solvent 1kg (1000g)
According to that: </span>

= 4.8 mole * 98 g/mole = 470g


m(H2SO4) which is =<span>470g
</span><span>m(solution) = m(H2SO4) + m(solvent) = 470 + 1000 = 1470 g
d(solution) = m(solution) / V(solution) =>
=> 1.249 g/mL = 1470 g / V(solution) =></span>
Answer: it’s B for edge !
Explanation: took the test
Answer:
74 g/mol
Explanation:
Using a periodic table, we can determine the molar mass by adding together 1 Ca, 2 O, and 2 H. This turns out to be approximately (40+32+2) = 74 g/mol
