Use n1/V1 = n2/V2

.1/2 = .4/V2
.1V2 = .8
V2 = 8 L or D

Answer:The new volume when 0.40 moles of gas are added to the balloon is 8 L.

Explanation:

Initial moles of gas n_1 = 0.10 moles

initial volume of the balloon, V_1 = 2.0 L

Final moles of gas n_2 = 0.40 moles

Final volume of the balloon, V_2 = 2.0 L

Avogadro Law:\frac{n_1}{V_1}=\frac{n_2}{V_2}

V_2=\frac{n_2\times V_1}{n_1}=\frac{0.40 mol\times 2.0L}{0.10 mol}=8.0 L

The new volume when 0.40 moles of gas are added to the balloon is 8 L.

Aleks04 [339]

Answer:

He is wrong . Most accurate is Buret .

Explanation:

The number of significant figure denotes the level of accuracy of a measurement .

Beaker can measure liquid in mL upto significant figure of 2 . That means it can measure volume in terms of 10 , 20 , 30mL etc . It can not measure 25 mL

accurately . The last figure of 28 mL is read by guess in the question . So it is not an accurate measurement .

Similarly , graduated cylinder can measure liquid upto significant figure of 3 .  That means it can measure volume in terms of 11 , 22 , 33 mL etc . It can not measure 25.5  mL accurately . The last figure of 28.3  mL is read by guess in the question . So it is less  accurate measurement .

Similarly , buret  can measure liquid upto significant figure of 4 .  That means it can measure volume in terms of 11.2 , 22.3 , 33.5 mL etc . It can not measure 25.53  mL accurately . The last figure of 28.32  mL is read by guess in the question . So it is most accurate among all the three instrument because it can measure accurately mL upto one tenth of it .
