0.8595g
Explanation:
According to the Standard International Units
1Kg = 1000g
Therefore, xKg = 95.5g
Solve for x
1 × 95.5 = x × 1000
95.5 = 1000x ( Divide both sides by 1000)
95.5/1000 = 0.0955
Therefore each magnet weighed 0.0955g
9 magnets will weigh 0.0955 × 9 = 0.8595 g
Therefore 9 magnets weigh 0.8595g or 859.5Kg
