0,2 кг * 75°С

It seems like you're looking to perform a calculation involving mass and temperature, possibly in the context of thermal energy or heat transfer.

If you are trying to calculate the thermal energy (Q) in joules, you can use the formula:

\[ Q = m \cdot c \cdot \Delta T \]

Where:

• \( Q \) = heat energy (in joules)
• \( m \) = mass (in kg)
• \( c \) = specific heat capacity (in J/(kg·°C))
• \( \Delta T \) = change in temperature (in °C)

However, from your message, it seems you're only providing the mass and temperature without context on the specific heat capacity or the change in temperature.

If you can provide more details—such as the specific heat capacity of the substance involved or the temperature change you are interested in—I can help you with a more specific calculation!
