Answer:

19.7 g.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to realize this problem can be solved by using a molecules-moles-mass relationship, starting with the given molecules, using the Avogadro's number and the molar mass of nitric acid (63.01 g/mol):

$18.8x10^{22}molec*\frac{1mol}{6.022x10^{23}molec}* \frac{63.01g}{1mol} \\\\=19.7g$

Regards!

How many g NaOH should be required to completely react 1.876 g of Copper (II) nitrate?

Doss [256]

$\\ \tt\hookrightarrow 2NaOH+Cu(NO_3)_2\longrightarrow 2NaNO_3+Cu(OH)_2$

Moles of copper nitrate:-

$\\ \tt\hookrightarrow \dfrac{1.876}{187.56}=0.001mol$

1mol of Copper nitrate reacts with 2mol NaOH
0.001mol will react with 0.002mol NaOH

Madd of NaOH

$\\ \tt\hookrightarrow 0.002(40)=0.08g$

Kate’s blood volume is 3.8L. Before treatment,if her blood glucose was 170 mg/dL, how many grams of glucose were in her blood?

LiRa [457]

Answer:

6.460 gm is the correct answer .

Explanation:

Given

Kate’s blood volume= $3.8L$

blood glucose= $170\ mg/dL$

As we know that

$1\ dL= 10^{-1}\ litre$

The $10^{-1}$ includes the blood glucose of the $170\ mg/dL,$

So $3.8L.$ of the Kate’s blood volume can be determined by

$=\ \frac{170 * 3.8 }{10^{-1} }$

$=170 * 38 \ mg$

$=6460\ mg$

To convert into the gm we have divided by the 1000

$6.460 \ gm$

Therefore the glucose in her blood=

$6.460 \ gm$

4Cr(s)+3O2 (g )= Cr2O3 (s) Find the theoretical yield in moles and grams

Assoli18 [71]

The balanced reaction is:

4Cr(s)+3O2 (g )= Cr2O3 (s)

Since we are not given the amount of any of the reactants, we assume we have one gram of chromium. Calculations are as follows:

1 g Cr ( 1 mol Cr / 52 g Cr ) ( 1 mol Cr2O3 / 4 mol Cr ) = 0.005 mol Cr2O3

0.005 mol Cr2O3 (151.99 g Cr2O3 / 1 mol Cr2O3 ) = 0.7307 g Cr2O3

Therefore, the theoretical yield for 1 gram of Cr is 0.005 mol Cr2O3 or 0.7307 g Cr2O3.

Metals are extracted from their ores.

zvonat [6]

1. Copper is very useful, so people want as much as possible.
2. We are running out, so we are extracting all the copper that we can to keep up with our needs.
