Relative formula mass of glucose? (C6H12O6)

Rom4ik [11]

To find the mass of glucose, you must multiply the atomic weight of each of the elements in the molecule by the subscripts in the formula:

$C_{6}=6*(12.01g)=72.06g$

$H_{12}=12*(1.008g)=12.096g$

$O_{6}=6*(15.999g)=95.994g$

Then you add all of them together:

$72.06g+12.096g+95.994g=180.15g$

Therefore, the molar weight of glucose is 180.15 grams.

If I have 7.0 x 10^24 formula units of magnesium chloride, how many grams of chlorine would I have?

REY [17]

Answer:

824 g

Explanation:

First we convert 7.0 x 10²⁴ formula units of magnesium chloride (MgCl₂) into moles, using Avogadro's number:

7.0 x 10²⁴ formula units ÷ 6.023x10²³ formula units/mol = 11.62 mol MgCl₂

There are two Cl moles per MgCl₂ moles, meaning that we have (2 * 11.62) 23.24 moles of Cl

Finally we convert 23.24 moles of chlorine into grams, using chlorine's molar mass:

23.24 mol * 35.45 g/mol = 824 g

Calculate the heat transferred to the system when 1.00 mol of a perfect gas expands reversibly at a

PSYCHO15rus [73]

Answer:

The heat transferred to the system is 1717.322 J

Explanation:

Given data:

n = moles of gas = 1 mol

T = temperature = 25°C = 298 K

Question: Calculate the heat transferred, Q = ?

$\frac{V_{2} }{V_{1} } =2$ (volume doubles due the gas expasion)

The heat transferred:

$Q=nRTln(\frac{V_{2} }{V_{1} } )$

Here

R = ideal gas constant = 8.314 J/mol K

$Q=1*8.314*298*ln(2)=1717.322J$
