Question

question 4 (1 point) calculate the % of sand if you had 6.85gm sand, 2.67g salt and 4.43 gm nh4cl in the mixture. a 26.7% b 49.1% c 31.7% d 68.5%

Explanation:

Step1: Calculate the total mass of the mixture

The total mass of the mixture is the sum of the masses of sand, salt, and \(NH_4Cl\).

$$
LATEXBLOCK0
$$

Step2: Calculate the percentage of sand

The formula for percentage is \(\text{Percentage}=\frac{\text{Particular component's mass}}{\text{Total mass}}\times100\).
For sand, \(\text{Mass of sand}=6.85\space gm\) and \(\text{Total mass}=13.95\space gm\)

$$
LATEXBLOCK1
$$

Answer:

B. \(49.1\%\)
