A lab team places 0.250g of an unknown solid acid in an Erlenmeyer flask. They neutralize the solid acid with 15.0ml of 0.210 M

Otrada [13]

Answer:

Molar mass of the unknown acid is 79 grams

Explanation:

We have to first get moles in 15.0 ml of sodium hydroxide solution:

${ \sf{1 \: l \: of \:NaOH \: contains \: 0.210 \: moles }} \\ { \sf{0.015 \: l \: of \: NaOH \: contain \: (0.015 \times 0.210) \: moles }} \\ { \underline{ = 0.00315 \: moles \: of \: NaOH}}$

since mole ratio of acid : base is 1 : 1, so;

moles of acid that reacted is 0.00315 moles of the unknown acid.

then we've to get molar mass:

${ \sf{0.00315 \: moles \: of \: acid \: weigh \: 0.250 \: g}} \\ { \sf{1 \: mole \: of \: acid \: weighs \: ( \frac{1 \times 0.250}{0.00315} ) \: g}} \\ { \underline{ = 79.4 \: g \approx79 \: grams}}$

In one on the compounds that contains only oxygen and nitrogen, 3.50 g of nitrogen combines with 2.00 g of oxygen. In another, 0

BigorU [14]

Answer:

Explanation:

The law of multiple proportions states that if two elements X and Y combine together to form more than one compound, then the several masses of X which chemically combine with a fixed mass of Y is in simple ratio.T

FIRST CASE ;

Molar mass of Nitrogen gas = 28 g/mol

Number of moles of Nitrogen gas = Mass/molar mass = 3.50/28 = 0.125 moles

Number of moles of Oxygen gas = Mass/molar mass = 2.00/32 = 0.0625 moles

Hence the ratio of number of moles of N2 to O2 will be 0.1295 : 0.0625 or 2:1

Similarly for the SECOND CASE ;

Molar mass of Nitrogen gas = 28 g/mol

Number of moles of Nitrogen gas = Mass/molar mass = 0.875/28 = 0.03125 moles

Number of moles of Oxygen gas = Mass/molar mass = 1/32 = 0.03125 moles

Hence the ratio of number of moles of N2 to O2 will be 0.03125 : 0.03125 or 1:1

pav-90 [236]

According to one acid base theory the forward reaction is classified as an acid base reaction because H2S is a H donor and CH3NH2 is a H acceptor.
According to the acid base theory; an acid is the proton donor or hydrogen ions donor while the base is the proton acceptor or hydrogen ion acceptor.
