LiCl

because Li loses 1 electron ==> Li+

and Cl gains 1 electron ==> Cl-

Li+ Cl-

we use the criss cross rule

===> LiCl

what concentration in parts per million in a solution that contains .008 grams of o2 dissolved in 1000 grams of water

julia-pushkina [17]

Ppm = mass of solute mg / mass of solvent kg

0.008 * 1000 = 8.0 mg ( solute )

1000 / 1000 = 1.0 kg (solvent )

ppm = 8 / 1

= 8.0 ppm

How many sucrose molecules will be in 250 grams

sasho [114]

<h2>Answer:</h2>

We will need to know Avogadro's number and the molar mass of sucrose for this problem to do dimensional analysis.

Avogadro's number: 6.022 × 10²³ molecules
Molar mass of sucrose: 342.2965 g/mol

250g × $\frac{1 mol}{342.297g}$ × $\frac{6.022 * 10^{23} molecules}{1 mol}$ = 4.398 molecules

There are <em>4.398 sucrose molecules </em>in 250 grams of sucrose.
