A volume of 60.0 mL of a 0.120 M HNO3 solution is titrated with 0.840 M KOH. Calculate the volume of KOH required to reach the e
german

Answer: 8.57 ml of KOH is required to reach the equivalence point.

Explanation:

To calculate the volume of acid, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid which is HNO_3

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base which is KOH.

We are given:

n_1=1\\M_1=0.120M\\V_1=60.0mL\\n_2=1\\M_2=0.840M\\V_2=?

Putting values in above equation, we get:

1\times 0.120\times 60.0=1\times 0.840\times V_2\\\\V_2=8.57mL

Thus 8.57 ml of KOH is required to reach the equivalence point.

. How many moles are there in 8.5x 1025 molecules of co2
bogdanovich [222]
1 mole => 6.023 x 10^23 molecules

x => 8.5 x 10^25 molecules

x = 8.5x10^25/ 6.023 x 10^23 = 141.1

A 4.16L balloon filled with gas is warmed from 251.5K to 298.4 K. What is the volume of the gas after it is heated?
MrRa [10]

Answer:Answer:5.95 LExplanation:V1/V2 = T1/T24.82 L/V2 = 243.1K/300.1KV2 = 4.82*300.1/243.1 L = 5.95 L

Explanation: The volume of the balloon is 400 m3. To what temperature must the air in the balloon be heated before the balloon will lift off. (Air density at 10 oC is 1.25 kg/m3.)
