Answer:

Density = 8.75ml

Explanation:

Density = Mass / Volume

In this problem ...

Mass = 28 grams

Volume = 31.4ml - 28.2ml = 32ml (water displacement also)

∴Density = mass /volume = 28g/32ml = 8.75g/ml

The mass percent of solute in a solution containing 3.73 g KBr dissolved in 131 g of H2O is:
Elina [12.6K]

\huge \underbrace \mathfrak \red{Answer}

28%

Explanation:

mass of solute(KBr) = 3.73g

mass of solvent(H2O) = 131g

mass of solution = mass of solute + mass of solvent

= 3.73 + 131

= 134.73g

\sf \large {mass \: percentage =  \frac{mass \: of \: solute}{mass \: of \: solvent}  \times 100} \\  \\  \sf  mass \: percentage =  \frac{3.73}{134.73}  \times 100 \\  \\  \sf mass \: percentage =  0.028 \times 100 \\  \\  \sf mass \: percentage = 28\%

Convert 1.39 x 10^24 atoms of carbon to moles of carbon
Nimfa-mama [501]
If 1mol ------- is ----------- 6,02×10²³
so x     ------- is ----------- 1,39×10²⁴

x=\frac{1,39*10^{24}*1mol}{6,02*10^{23}}\approx2,31mol
