Answer:

Water is a covalently bonded molecule. H2O-> Oxygen and hydrogen are both nonmetals. Ionic compounds are made up of a nometal and metal which causes it to have electrical components. A covalent bond is stronger than an ionic bond, which allows water to break down ionic salts.

3.25 x 10+8 nm2 divide by 6.5 x 10+6 nm =

Vesnalui [34]

Answer: 50 nm

Explanation: Two steps:

1. Divide 3.25/6.5 = 0.5

2. Divide 10^8/10^6 = 10^2

nm^2/nm = nm

Combine: 0.5x10^2 nm

or 50 nm

2. 27.8 mL of an unknown were added to a 50.0-mL flask that weighs 464.7 g. The total mass of the flask and the liquid is 552.4

agasfer [191]

Answer:

$d=4.24x10^{-4}\frac{lb}{in^3}$

Explanation:

Hello there!

In this case, according to the given information, it turns out firstly necessary for us to set the equation for the calculation of density and mass divided by volume:

$d=\frac{m}{V}$

Thus, we can find the mass of the unknown by subtracting the total mass of the liquid to the mass of the flask and the liquid:

$m=552.4g-464.7g=87.7g$

So that we are now able to calculate the density in g/mL first:

$d=\frac{87.7g}{27.8mL}=3.15g/mL$

Now, we proceed to the conversion to lb/in³ by using the following setup:

$d=3.15\frac{g}{mL}*\frac{1lb}{453.6g}*\frac{1in^3}{16.3871mL}\\\\d=4.24x10^{-4}\frac{lb}{in^3}$

Regards!
