A triangle has a=6 b=8 c=? Answer: The value of c = 10. Step-by-step explanation: Given: a=6 b=8 Asked: c = ? Formula: c² = a² + b² Solution: In solving this problem use the Pythagorean theorem. c² = a² + b² c² = 6² + 8² c² = 36 + 64 c² = 100 c = 10 Therefore, the value of c = 10.
What is the volume occupied by 0.25 mol of a gas at STP? Good Day... Problem: What is the volume occupied by 0.25 mol of a gas at STP? Note: Every 1 mole of any gases will occupy a volume of 22.4 L at STP. 22.4 L = 1 mole Given Data: volume of gas = ? unknown amount of gas = 0.25 mole conversion factor = 22.4 L/1 mol Solution: Multiply the given amount of gas by the conversion factor. Volume of gas at STP = 0.25 mol × 22.4 L / 1 mol (cancel the unit mol) = 5.6 L Answer: A volume of 0.25 mol of gas at STP is = 5.6 L Hope it helps...=)
