The stock concentration of NaOH is 0.5M. 0.5M = 0.500mol/1.0L.

valentinak56 [21]

Answer:a) 0.1 mole. b) 4g. c) 2% d) 196 mL

Explanation: in 200mL , 0.1mole

mw NaOH = 40g/mol —> 4g in 0.1 mole

4g in 200mL so 2g in 100mL

density NaOH = 1g/mL so if 4g in 200 mL, 4mL , 196 mL water

A sample of lead has a density of 11.3 g/cm3 and a mass of 123 grams, what is the volume of the sample?

SVEN [57.7K]

Answer:

The answer is

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = \frac{mass}{density} \\$

From the question

mass = 123 g

density = 11.3 g/cm³

The volume is

$volume = \frac{123}{11.3} \\ = 11.18181818...$

We have the final answer as
