Answer:

0.895 g/mL

Explanation:

Step 1: Given data

Mass of liquid Z (m): 2.763 lb

Volume of liquid Z (V): 5.93 cups

Step 2: Convert "m" to grams

We will use the relationship 1 lb = 453.59 g.

$2.763 lb \times \frac{453.59 g}{1lb} = 1,253g$

Step 3: Convert "V" to milliliters

We will use the relationship 1 cup = 236.59 mL.

$5.93cup \times \frac{236.59mL}{1cup} = 1.40 \times 10^{3} mL$

Step 4: Calculate the density of the liquid Z

The density (ρ) of the liquid Z is equal to its mass divided by its volume.

$\rho = \frac{m}{V} = \frac{1,253g}{1.40 \times 10^{3}mL } = 0.895 g/mL$

In a solution at 25 degrees Celsius the H is 3.5 x 10^-6 M. What is the OH

antiseptic1488 [7]

Answer:

Explanation:

[ H⁺] = 3.5 x 10⁻⁶ M .

[ H⁺] [ OH⁻] = 10⁻¹⁴

[ OH⁻] x 3.5 x 10⁻⁶ = 10⁻¹⁴

[ OH⁻] = 2.857 x 10⁻⁹ M .
