7*0.23 =1.61 pints of alcohol in 7 pints of 23% solution
3*0.7 =2.1 pints of alcohol in 3 pints of 70% solution
10x = pints pf alcohol in 10-pint mixture

7*0.23+3*0.7=10x
1.61+2.1=10x
3.71 = 10x
x = 0.371 = 37.1% is the concentration of the new 10-pint mixture

HELP 20 POINTS <br>A photon has a wavelength of 366 nm. What is the frequency of this photon?​
den301095 [7]

Answer:

9.  8.2x10¹⁴ Hz

Explanation:

Wavelength λ = 366 nm

Formula: Frequency = C / λ

To find the wavelength in m,

1 nm = 1.0x10⁻⁹ m

So, 366 nm = ?

= 3.66x10⁻⁷ m

Frequency = 3.0x10⁸m.s-1 / 3.66x10⁻⁷ m

                  = 8.2x10¹⁴ s-1

the volume of gas in a container was originally 3.24L, while at standard pressure 1.00 atm. what will the volume be if the press
Simora [160]
Hello!

To solve this problem, we will use the Boyle's Law, which describes how pressure changes when volume changes and vice-versa. The equation for this law is the following one, and we'll clear for V2:

P1*V1=P2*V2 \\ \\ V2= \frac{P1*V1}{P2}= \frac{3,24 L * 1 atm}{1,20 atm}= 2,7 L

So, the final volume after increasing the pressure would be 2,7 L. That means that volume decreases when the pressure increases

Have a nice day!
