Chemistry
1 answer:
Anni [7]2 years ago
4 0

Answer:

\Large \boxed{\sf 34.2 \ g}

Explanation:

Mole ratio

9:4

1.75:x

Moles of CO₂

\displaystyle \frac{4 \times 1.75}{9} =0.78

Use formula to find mass

\displaystyle moles=\frac{mass}{M_r}

Relative molecular mass of CO₂ = 12 + 16 × 2 = 44

\displaystyle 0.78=\frac{mass}{44}

mass=34.2

What is 10 times as many as 1 hundred is blank hundred or blank thousand ?
Rama09 [41]

10 times as many as 1 hundred is 10 hundred or 1 thousand.

This is the question of simple multiplications related to a place value system.

The given equation in unit form can be rewritten as:

10 × 1 × 100 = (X × 100) or (Y × 1000)

Arranging in two parts, we get,

10 × 1 × 100 = X × 100           ........(1)

10 × 1 × 100 = Y × 1000         ........(2)

Now, calculating the value of X and Y,

From equation (1), we get,

10 × 1 × 100 = X×100

or, 1000 = X × 100

or, X = 10

Hence, 10 times as many as 1 hundred is 10 hundred.

Similarly, from equation (2). we get,

10 × 1 × 100 = Y × 1000

or, 1000 = Y × 1000

or, Y = 1

Hence, 10 times as many as 1 hundred is 1 thousand.

Therefore, 10 times as many as 1 hundred is 10 hundred or 1 thousand.

If 2.5L of solution is diluted to prepare 1.7L of a 0.8M solution, what was the original concentration?
mamaluj [8]

Answer:

0.544 M

Explanation:

First find the moles in the final solution

0.8 mols/L *1.7L

1.36 mols

so there is 1.36 mols in 2.5L

concentration will be 1.36/2.5

0.544 M

Which set of coefficients will balance this chemical equation?
Katarina [22]

Answer:

B 1,3

Explanation:

Count the atoms on each side of the arrow, they have to be equal

After arrow

2x C

6x O

4x H

Before the arrow

2x C - correct, as it is the only compound with C then there must only be 1 mole of it.

This is also the correct amount of H

We need 6x O total so 6/2 = 3

So there are 3 moles of O
