Answer:
100 g
Explanation:
We know the concentration is 200 g/L.
Convert 500mL to L: 500mL/1000mL = 0.5 L
Now, multiply this by 200 to cancel out the L units and get grams:
200 g/L * 0.5 L = 100 g
Thus, the answer is 100 grams.
Hope this helps!
Answer:
1 g/mL.
Explanation:
From the question given above, the following data were obtained:
Volume = 100 mL
Mass = 100 g
Density =?
Density of a substance is simply defined as the mass of the substance per unit volume of the substance. The density can be expressed mathematically as:
Density (D) = mass (m) / volume (V)
D = m / V
With the above formula, we can obtain the density of the liquid as follow:
Volume (V) = 100 mL
Mass (m) = 100 g
Density (D) =?
D = m / V
D = 100 / 100
D = 1 g/mL
Thus, the density of the liquid is 1 g/mL

Explanation:
Answer:
The procedure for calculating the pH of a solution of a weak base is similar to that of the weak acid in the sample problem. However, the variable x will represent the concentration of the hydroxide ion. The pH is found by taking the negative logarithm to get the pOH, followed by subtracting from 14 to get the pH.
