Answer:
mass = 58.944 g
Explanation:
Given data:
Number of moles of SO₂ = 0.921 mol
Mass of SO₂ = ?
Solution:
Formula:
Number of moles = mass/ molar mass
First of all we will calculate the molar mass.
SO₂ = 32 + 16×2 = 64 g/mol
Now we will put the values in formula.
Number of moles = mass/ molar mass
0.921 mol = mass /64 g/mol
mass = 0.921 mol × 64 g/mol
mass = 58.944 g
Convert each amount of grams into moles:
I: 23.24g x 1 mol / 126.90g = 0.1831 mol I
C: 2.198 x 1 mol / 12.01g = 0.1830 mol C
N: 2.562 x 1 mol / 14.01g = 0.1829 mol N
Each element has roughly the same amount of moles, which means the whole number ratio between the elements is 1:1:1
Therefore the empirical formula is ICN
I would say D. Because if you displace too much water it would would either go to fast or not move at all... that's just my thought
Answer:
0.213 J/g°C
Explanation:
To calculate specific heat of the metal, the formula is used:
Q = m × c × ∆T
Where Q = amount of heat
m = mass
c = specific heat
∆T = change in temperature
According to this question, Q = 37.7 J, m= 12.5 g, initial temperature= 19.5 °C, final temperature = 33.6°C, c=?
Q = m × c × ∆T
37.7 = 12.5 × c × (33.6-19.5)
37.7 = 12.5c × 14.1
37.7 = 176.25c
c = 37.7/176.25
c = 0.2139
Hence, the specific heat of the metal is 0.213 J/g°C
