Answer:

The Similarities Between Mechanical Waves and Electromagnetic Waves. Some similarities between mechanical waves like sound and electromagnetic waves like light are: Both wave types are defined by their frequency. The higher the frequency, the less distance between successive crests of a wave (aka wavelength).

A 3.20-mol sample of gas occupies a volume of 350. mL at 300.0 K. Determine the

nalin [4]

Answer:

$P \approx 225atm$

Explanation:

From the question we are told that:

Moles of sample n=3.20_mol

Volume V=350mL

Temperature T=300k

Generally the equation for ideal gas is mathematically given by

$PV=nRT$

$P=\frac{nRT}{V}$

$P=\frac{3.20*0.08206*300}{350*10^{-3}}$

$P=225.079atm$

$P \approx 225atm$

How many moles are in 2.5L of 1.75 M Na2CO3

Natasha_Volkova [10]

Answer:

4.4 mol.

Explanation:

Hello!

In this case, since the formula for calculating the molarity is:

$M=n/V$

Whereas n stands for moles and V for the volume in liters; we can solve for n as shown below when we are given the volume and the molarity:

$n=V*M$

Thus, we plug in the given data to obtain:

$n=2.5L*1.75mol/L=4.4mol$

Best regards!
