How many inches in 745mm?

By unit of length and distance and conversion ,we can say that 1 mm =0.03930 in 745 mm=29.33 in


When a sealed bulb containing gas is immersed in an iced bath it has a gas pressure of 345 torr When the same bulb is place in an oventhe pressure of the gas rises to 745 Torr calculate the ovens temp?

The absolute temperature of the oven is 745/345 times the absolute temperatureof the ice bath.(745/345) x (273.15 K) = 589.85 K = 316.7° C.


What volume will 155 g of butane occupy at 745 torr and 35 C?

To find the volume of 155 g of butane (C₄H₁₀) at 745 torr and 35°C, we can use the Ideal Gas Law, PV = nRT. First, convert the mass of butane to moles (molar mass ≈ 58.12 g/mol), giving us about 2.67 moles. Then, convert the pressure to atm (745 torr ≈ 0.978 atm) and the temperature to Kelvin (35°C ≈ 308 K). Finally, using R = 0.0821 L·atm/(K·mol), we calculate the volume: V = nRT/P, which results in a volume of approximately 67.5 liters.


What is the cost of generating 745 watts of electricity?

It depends on how long it lasts because you pay for energy, and that is power times time. 745 watts generated for 1 hour would use 745 watt-hours of energy (in practice often 2-3 times more than that because power is lost in the generation process). 1000 watt-hours is called a kilowatt-hour, and that is also known as a Unit, which is the form in which it appears on electricity bills. Generation costs vary widely but the selling price is around £0.15 per unit, so the direct costs of generation are less than that for most tpes of generation.


How far is mercury's inner core?

Mercury's inner core is estimated to be about 1,200 to 1,500 kilometers (745 to 932 miles) below the planet's surface. Mercury is a small and dense planet, resulting in a relatively large and proportionally deep core compared to its overall size.
