1) Find the molar mass of sucrose: 12*12 + 22*1 + 11*16 = 342 g/mol

2) Multiply the molar mass by the number of mols: 0.185 mol * 342 g/mol = 63.27 g

A ballon begins at sea level at 1 atm. It rises in the atmosphere to where the pressure is lower, to where the pressure is .75 a
maxonik [38]

Answer:

Original volume=3L

Explanation:

Assuming the gas in the ballon is ideal and the temperature does not vary with height  we have the gas law as

PV=nRT

Here RHS is constant in both the conditions which means

PV=constant

Given P1=1 atm V1=V  P2=0.75atm V2=4L

P1V1=P2V2

1*V=0.75*4

V=3L

The initial volume of the gas is 3L

Answer all 5 questions, please
klemol [59]
1.) protons neutrons and electrons

2.) a wall outlet it is made up of metal that conducts heat. When when heat is applied it provides enough energy to these electrons

3.) is an imbalance if electric charges within or on the surface of a material

4.) static electricity decoded tiny changes in the surface of a balloon causes it to charge more when rubbed against our hair

5.) you might have to answer that on your own but if you don’t want to here’s my experience


One day me and my twin brother were jumping on the trampoline and when we fell down my hair rubbed against the surface of it and stuck up

Hope that helped and Brainiest?

I just started learning about kinetic molecular theory, and I’m not sure how to answer the question circled below
lions [1.4K]

Answer : The value of 'R' is 0.0821\text{ L atm }mol^{-1}K^{-1}

Solution : Given,

At STP conditions,

Pressure = 1 atm

Temperature = 273 K

Number of moles = 1 mole

Volume = 22.4 L

Formula used :     R=\frac{PV}{nT}

where,

R = Gas constant

P = pressure of gas

T = temperature of gas

V = volume of gas

n = number of moles of gas

Now put all the given values in this formula, we get the values of 'R'.

R=\frac{(1atm)\times (22.4L)}{(1mole)\times (273K)}

R=0.0821\text{ L atm }mol^{-1}K^{-1}

Therefore, the value of 'R' is 0.0821\text{ L atm }mol^{-1}K^{-1}.
