1. 3.311 * 10^24 particles=_moles? 2. 126 grams of H2O =________moles of moles? whats the answers

1 answer:

4 0

1. You can use Avogadro’s number, 6.022x10^23 atoms/mole, to answer this one.

(3.311x10^24/6.022x10^23) = 5.498 moles of substance

2. H2O has a formula weight approximately equal to 18 grams. Dividing the given amount by the formula weight of water will tell us the number of moles present.

126/18 = 7 moles H2O

Determine two complex numbers, (a+bi) and (c+di), where a and d are irrational numbers and b and c are rational number

Dafna11 [192]

Answer:

The two complex numbers are $\sqrt2 + 5i \text{ and } 6 + \sqrt5i$

Explanation:

We have to form two complex numbers of the form

$a + ib\\c + id$

such that and d are irrational numbers and b and c are rational numbers.

We know that $\sqrt2, \sqrt3$ are irrational numbers.

5 and 6 are rational numbers.

We put

$a = \sqrt2\\b = 5\\c = 6\\d = \sqrt5\\a+ib = \sqrt2 + 5i\\c + id = 6 + \sqrt5i$

Thus, the two complex numbers are: $\sqrt2 + 5i \text{ and } 6 + \sqrt5i$

Kia is doing an experiment in science lab. She is given a beaker containing 100 g of liquid. The beaker has markings on the side

vlabodo [156]

The key to solving this problem is density. Density determines the mass of a molecule for a certain volume. Kia is given a beaker containing 100 g which volume is at 100 mL mark. Then the density of the liquid would be:
density=mass/volume
density= 100g/ 100ml= 1g/ml

If the water now comes up to the 50 mL mark, then the weight would be:
density = mass/volume
mass = volume * density
mass = 50ml * (1g/ml)= 50g
