How many grams of glucose are needed to prepare 144.3 mL of a 1.4%(m/v) glucose solution?

Montano1993 [528]

Answer:

2.0202 grams

Explanation:

1.4% (m/v) glucose solution means: 1.4g glucose/100mL solution.

so ?g glucose = 144.3 mL soln

Now apply the conversion factor, and you have:

?g glucose = 144.3mL soln x (1.4g glucose/100mL soln).

so you have (144.3x1.4/100) g glucose= 2.0202 grams

The volume of a sample of <img src="https://tex.z-dn.net/?f=P_b" id="TexFormula1" title="P_b" alt="P_b" align="absmiddle" class=

murzikaleks [220]

Answer : The mass of sample is, 267.5 grams.

Explanation :

Density : It is defined as the mass of a substance contained per unit volume.

Formula used :

$Density=\frac{Mass}{Volume}$

Given:

Volume of Pb = $23.57cm^3$

Density of Pb = $11.35g/cm^3$

Now put all the given values in the above formula, we get the mass of Pb.

$11.35g/cm^3=\frac{Mass}{23.57cm^3}$

$Mass=267.5195g=267.5g$

Therefore, the mass of sample is, 267.5 grams.
