Hello!
Answer:
Explanation:
→ The force applied to an object is equal to:
Where:
- a is the acceleration
- F is the force
- m is the mass
→ So, the acceleration of the car is equal to:
Conclusion:
The acceleration of the car is 1.30m/s².
Explanation:
acceleration is directly proportional to the force and inversely proportional to the mass of the object
a=f/m
=1700/1300

The number of moles in 987 grams of Ra(OH)2 = 3.8 moles
Ra = 226g
O= 16g
H = 1
Therefore molar mass of Ra(OH)2= 226+ (16+1)×2
= 260g/mol
The molar mass of Ra(OH)2 = 260g/mol
Thus means that 260g of Ra(OH)2 makes up 1 mole
Therefore, 987 g = X moles
Make X moles the subject of formula,
X mole = 987/260
= 3.8 moles
Therefore, the number of moles in 987 grams of Ra(OH)2 = 3.8 moles

Answer : 3.79 moles are in 987 grams of .
Solution : Given,
Mass of = 987 g
Molar mass of = 260 g/mole
Now we have to calculate the moles of .
Formula used :
Now put all the given values in this formula, we get the moles.
Therefore, 3.79 moles are in 987 grams of .
