6. Describe how you would make 250 mL of a 4.5 M silver nitrate solution. SHOW ALL CALCS.
Archy [21]

Answer:

Dissolve 190 grams of silver nitrate in 250 mL of water.

Step-by-step explanation:

First, find the moles of AgNO₃ from the volume and concentration.

0.250 L × 4.5 mol/L = 1.125 mol

Next, find the mass of AgNO₃ using the molar mass.

1.125 mol × 170 g/mol = 191.25 g

Rounded to two significant figures, dissolve 190 grams of silver nitrate in 250 mL of water.

This is about scientific notation. Can someone plzzzz help I’m confused
MariettaO [177]

Answer: Carat

Step-by-step explanation:

It is given that 1 atomic unit is equivalent to

8.3\times 10^{-24}\ \text{carat} and 1.66\times 10^{-21}\ mg

Express carat and milligram in the atomic mass unit, that is

1\ \text{amu}\equiv 8.3\times 10^{-24}\ \text{carat}\\1\ \text{carat}\equiv \dfrac{1}{8.3\times 10^{-24}}=1.204\times 10^{23}\ amu

For milligram

1\ \text{amu}\equiv 1.66\times 10^{-21}\ mg\\1\ mg\equiv \dfrac{1}{1.66\times 10^{-21}}=6.02\times 10^{20}\ \text{amu}

clearly, carat is greater than milligram
