Question

1. calculate the mass in grams to prepare a 10mg/ml solution of albumin in 30 ml using a stock solution of 0.5g/ml of albumin solution. report your answer to 2 decimal places.

Explanation:

Step1: Identify the formula

$m = c\times V$, where $m$ is mass, $c$ is concentration, $V$ is volume.

Step2: Determine the values

$c = 10\ mg/mL$, $V=30\ mL$.

Step3: Calculate the mass in milligrams

$m = 10\ mg/mL\times30\ mL = 300\ mg$.

Step4: Convert milligrams to grams

Since $1\ g= 1000\ mg$, then $m=\frac{300\ mg}{1000}=0.30\ g$.

Answer:

0.30
