loris [4]2 years ago
7 0

Answer:

7.78moles of O2

Explanation:

2H2 (g) + O2 (g) → 2H2O (g)

From the balanced equation,

2 moles of H2 required 1mole of O2.

Therefore, 15.56 moles of H2 will require = 15.56/2 = 7.78moles of O2

Write this number in standard notation.<br> 1.986 x 10negative exponent 6 or 1.986 x 10^6
Brums [2.3K]

Answer:

0.000001986

Explanation:

We have the number 1.986*10^{-6}. Standard notation would basically be this number without the 10^{-6} part.

To get rid of this part, we need to move the decimal point 6 places to the left (we go left because it's negative 6, indicating division).

So, when we move the decimal point 6 places to the left, the resulting number is: 0.000001986, with 5 zeros after the decimal point before a nonzero number.

Thus, the answer is 0.000001986.

How many moles of tin,Sn, are in 2500 atoms of tin?
Assoli18 [71]

Answer:

4.15×10⁻²¹ moles of Sn

Explanation:

This question can be solved by a simple rule of three.

We know that 1 mol contains 6.02×10²³ particles.

In this case, our particles are the atoms, so:

6.02×10²³ atoms / 1 mol . 2500 atoms = 4.15×10⁻²¹ moles.

The knowledge of mol can be applied for everything:

A mol of molecules

A mol of atoms

A mol of a compound
