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.

How do I figure out how to find the solutions to the system of equations

OlgaM077 [116]

Answer:

This system of equations has no solution.

Step-by-step explanation:

Solving a system of equations can be done using a few different methods. Since your second equation is already solved for 'y', you can substitute this expression (- $\frac{1}{2}$ x + 3) for the value of 'y' in the first equation:

2x + 4(- $\frac{1}{2}$ x + 3) = 10

Distribute: 2x - 2x + 12 = 10

Combine like terms: 0 + 12 = 10 or 12 ≠ 10

Since the variables cancel out and 12 ≠ 10, there are no solutions to this system.
