A 2.0% (w/v) solution of sodium hydrogen citrate, Na2C6H6O7, which also contains 2.5% (w/v) of dextrose, C6H12O6, is used as an
tamaranim1 [39]

Answer:

0.0847M is molarity of sodium hydrogen citrate in the solution

Explanation:

The 2.0%(w/v) solution of sodium hydrogen citrate contains 2g of the solute in 100mL of solution. To find the molarity of the solution we need to convert the mass of solute to moles using molar mass and the mL of solution to Liters because molarity is the ratio between moles of sodium hydrogen citrate and liters of solution.

<em>Moles Na2C6H6O7:</em>

<em>Molar Mass:</em>

2Na: 2*22.99g/mol: 45.98g/mol

6C: 6*12.01g/mol: 72.01g/mol

6H: 6*1.008g/mol: 6.048g/mol

7O: 7*16g/mol: 112g/mol

45.98g/mol + 72.01g/mol + 6.048g/mol + 112g/mol = 236.038g/mol

Moles of 2g:

2g * (1mol / 236.038g) = <em>8.473x10⁻³ moles</em>

<em />

<em>Liters solution:</em>

100mL * (1L / 1000mL) = <em>0.100L</em>

<em>Molarity:</em>

8.473x10⁻³ moles / 0.100L =

What is the major cause of erosion and weathering that affects coastline features?
Arisa [49]

Answer:

Image result for What is the major cause of erosion and weathering that affects coastline features?

Coastal erosion, which is the wearing away of coastal land or beaches, is mainly caused by the impact of waves along the shoreline. This is accentuated during storms when waves are large and crash on shore with a lot of energy. ... As the sand and rocks crash into the coast, they grind away land and rock.

A 170.0 g sample of an unidentified compound contains 29.84 g sodium, 67.49
GREYUIT [131]

The empirical formula : Na₂Cr₂O₇

<h3>Further explanation</h3>

Given

170 g sample contains :

29.84 g sodium, 67.49  g chromium, and 72.67 g oxygen

Required

The compound's empirical formula

Solution

mol ratio of elements :

Na : 29.84 : 23 g/mol = 1.297

Cr : 67.49 : 51,9961 g/mol = 1.297

O : 72.67 : 16 g/mol = 4.54

Divide by 1.297

Na : Cr : O = 1 : 1 : 3.5 = 2 : 2 : 7

sergij07 [2.7K]
The balanced reaction is:

<span>Cu + 2AgNO3 = 2Ag + Cu(NO3)2

We are givent the amount of silver to be produced. This will be the starting point. Calculations are as follows:

</span><span> 3.50 mol Ag ( 1 mol Cu / 2 mol Ag ) = 1.75 mol Cu
</span>
Therefore, we need 1.75 mol of copper in order to produce 3.50 mol of silver.
