An enzyme is a biological catalyst that speeds up chemical reactions without altering its equilibrium. the correct answer is c
Answer:
m = 575 g
Explanation:
Given data:
Volume of solution = 0.500 L (0.500×1000 = 500 mL)
Density of glucose solution = 1.15 g/mL
Mass of glucose solution = ?
Solution:
Formula:
d = m/v
d = density
m = mass
v = velocity
Now we will put the values in formula.
1.15 g/mL = m/500 mL
m = 1.15 g/mL × 500 mL
m = 575 g
Answer:
7.34684 × 10^23 atoms
Explanation:
Well, one mole is basically
6.022 × 10^23 atoms. So 1.22 moles would be
6.022 × 10^23 ⋅ 1.22 atoms.
6.022 × 10^23 ⋅ 1.22 = 7.34684 × 10^23 atoms
