What is the potential energy of a rock that weights 100 Newtons that is sitting on top
weqwewe [10]

Answer:

Us we know mass is constant any where .

Given :-

W=100N                                               gravity=G=10 meter per second square

H=300M

W=M*G

w=m*10m/second square

100=M*10

M=10kg

P.E=M*G*H

P.E=10*10*300

P.E=30,000J

When 0.215 mol of a gas is placed into a 34.25 mL container at 125.0°C, 1
horrorfan [7]

Answer:

205.12 atm

Explanation:

Using the ideal gas law equation:

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

R = 0.0821 Latm/perK)

T = temperature (K)

n = number of moles (mol)

According to the information in this question;

P = ?

V = 34.25 mL = 34.25 ÷ 1000 = 0.03425L

n = 0.215 mol

T = 125.0°C = 125 + 273 = 398K

Using PV = nRT

P = nRT ÷ V

P = (0.215 × 0.0821 × 398) ÷ (0.03425)

P = 7.025 ÷ 0.03425

P = 205.12 atm
